Here is a question for the engineers amongst us. I have a UHF receiver rated at 8 watts of power consumption. The receiver uses passive ventilation and has slots in the top of the case to exhaust hot air.

 

I also have a cat. The cat possesses thick fur of intermediate length. The cat enjoys lying on top of the UHF receiver because of the heat it radiates. When the cat lies on the receiver, it completely blocks all of the upper ventilation slots.

 

My question is if the cat is capable of damaging the receiver by lying on it. Even better, can anyone calculate the likely temperature rise of internal components due to the presence of the cat, and what the probable time to component failure might be?

 

The name of the cat is Eeny.

If you shortened the cat's name, that would increase the airflow and reduce the temperature of the receiver ;-)

To get an accurate estimate then would have to know things like what the casing is made of, what is the size of the box, what is inside the box, the chip specs, etc.

 

Why not just put a thermometer or temperature probe into the unit?

Two things to also consider:

 

1) What is the cats main diet?

 

2) Is the unit capable of, or does it actually serve up a daily dose of prawn through its menu?

 

Point 2 especially, has the potential to raise temperatures over and above what may be considered normal.

What is the square meterage of the cat? Diameter? Thickness at its roundest part?

Show some compassion man, it's a cat, not a unit!!
(And a quick Google will tell you how hot a cat gets ;-) )

Yes, it will stuff it.

 

My cats like to sleep ontop of the games consoles when they are on, then the reduced airflow makes it crash or whatever and I come back into the room with a crashed game and a warm cat.

I was hoping for just an educated best guess. Unfortunately I forgot about the engineer's need for pedantry. The cat's diet is difficult to measure as it includes unknown quantities of rat, mouse and bunny. No prawns to the best of my knowledge. The cat is also difficult to measure as it is uncooperative.

Build a cage around the cat or the receiver. Think inside the box. ;)

Turn the receiver off. Save money *and* it won't overheat *and* the cat will go sleep on top of your computer. Win-win-win.

Funniest thread I've read in quite a while :-)

 

Think of it like a variation of Schroedinger Cat.

 

You wont know the damage is done until the damage is done.

 

BTW, what happened to Miney and Mo ?

We've done this for other reasons: putting a plastic or metal in/out tray upside down over the device.

Rats, mice and rabbits indicate a killer what.

Best idea yet, plus the only non humorous one, but an ideal and cheap solution. Black tray to match the device too so it doesnt look quirky

The cat on the STB does not belong to Schroedinger but it has been observed and is definitely alive. Unfortunately Miney is no longer with us. She disappeared some time ago. I miss her and continue to hope she will show up one day. Moe is still part of the family but he is too big to fit on the STB and he doesn't even try.
